Novel compound feed for fish-shrimp mixed culture

Abstract

The invention discloses a novel compound feed for fish-shrimp mixed culture. The novel compound feed is prepared from the following components in mass percent: 5%-8% of housefly protein, 3%-5% of chicken meal, 5%-10% of peeled soybean meal, 5%-10% of molasses yeast, 20%-25% of high gluten flour, 20%-30% of DDGS (distillers dried grains with soluble), 20%-25% of rapeseed meal, 1%-2% of monocalcium phosphate, 3%-5% of soyabean phosphatide oil, 1% of vitamin premix, and 1% of mineral substance premix. According to the feed formula, the dependence on fish meal and cuttlefish paste is eliminated, the novel compound feed has the characteristics of high efficiency, environment protection and sustainable development, and the feed cost can be reduced greatly; and the compound feed has comprehensive nutrition and strong feeding attraction property, is high in palatability, can promote growth, has low feed coefficient and can release the growth potential of shrimps to the maximum extent, the breeding cost is reduced and the economic returns are improved.

Description

technical field [0001] The invention relates to a mixed feed for fish and shrimp, which belongs to the technical field of compound feed, in particular to a novel mixed feed for fish and shrimp. Background technique [0002] In recent years, due to environmental pollution, climate change, and degradation of prawn germplasm, the production of prawns in my country has declined by 9.7% from 2010 to 2012. In 2013, due to the ravages of shrimp diseases, the production of prawns in Southeast Asia production areas dropped by at least 40%, and the production of prawn feed in my country dropped from 1.65 million tons to 1.33 million tons. [0003] In response to the above phenomenon, the majority of farmers in my country have explored the polyculture model of fish and shrimp, realized biological control, achieved good breeding results, and the breeding area is also expanding day by day. Guang, Taiping, Zhuhai Pingsha prawns are mixed with tilapia, Zhanjiang three islands are mixed wit...

Problems solved by technology

However, the quality of mixed feed for fish and shrimp in the market is uneven, either the cost is too high (contains high fishmeal), or the feeding effect is too poor (a large amount of fillers are used, poor food attraction and water resistance), so a new type of high-efficiency feed is developed. Environmentally friendly fish and shrimp mixed feed is imminent
